SETI-I WHEELER, OF CASTLETON, NEW YORK.

OVAL ROLL AND CORE THEREFOR.

To all whom 'it may concern:

Be it known that I, SE'rH lWHEELER, a citizen of the United States, anda resident of Castleton, county of Rensselaer, and State of New York,have invented certain new and useful Improvements in Oval Rolls andCores Therefor, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in oval rolls and cores therefor ofthe character adapted to be employed in a certain class of oscillatingor rotating fixture employed in toilet rooms, and the objects of myinvention are first, to compel the mounting of the roll in the properrelative position in the fixture; second, to facilitate the mounting ofthe roll in position; and third, to improve and simplify theconstruction of the core and reduce the cost of manufacture thereof.

To these ends my invention consists first, in a core provided with asubstantially Hat opening from end to end thereof disposed eccentricallywidth-wise with respect thereto, one of the side edges of the openingbeing arranged in part or in whole at a different angle to the axis ofthe core than the other; and second, in a core constructed of two flatsheets in contact throughout except where they are offset to form theopening, the two sheets being provided with interlocking portionsadjacent the opening, to secure them together.

In order that my invention may be thoroughly understood, I .will nowproceed to describe an embodiment thereof, having reference to theaccompanying drawings illustrating the same, and will then point out thenovel features in claims.

In the drawings: Figure 1 is a view in central transverse sectionthrough an oval roll provided with a core constructed in accordance withmy invention. Fig. 2 is a face view of the core removed from the roll.Fig. 3 is a view in central transverse section through a core upon anenlarged scale. Fig. 4i is a face view of the blank from which the coreis constructed, showing the same before it has been folded to form thecore. Fig. 5 is a View of a modified form of the core.

Specification of Letters Patent.

Application led March 4, 1910.

Patented Oct. 11, 1910. serial No. 547,203.

The oval roll in its entirety comprises a core 10 and a strip of paper11 wound thereon. The core is substantially fiat so that the rollassumes the form of a substantially fiat oval. The roll is intended tobe supported eccentrically in a fixture provided for the purpose, andfor the purpose of mounting it in the fixture the core is provided withan opening 12 extending longitudinally therethrough from end to end, thesaid opening being made of a size and shape to fit a rotating oroscillating supporting plate with which the fixture is provided. Thisopening 12 is located eccentrieally width-wise of the core so that theroll will always tend to hang in a predetermined relative position. Inorder to compel the mounting ofthe roll in the proper position withrespect to the hanger, I first taper the opening width-wise, the taperedform being designed to correspond with a similar taper of the supportingplate; and second, I dispose the longitudinal edge either in whole or inpart, at one side of the opening at a different angle with respect tothe axis of the core to that of the other edge, the same also beingdesigned to correspond to the form and shape of the hanger. The taperedform of the opening will insure the roll being inserted in the hanger atthe proper end, while the relative angularity of the edges will compelthe roll being placed in position upon the hanger the right way up.Heretofore it has been necessary to give the attendants explicitinstructions as to how to mount the rolls in the fixtures. Theseinstructions were sometimes followed and sometimes not, but in eithercase delay or confusion, or both, was the result. By my presentinvention the roll must be mounted properly in the hanger for it cannotbe mounted in any but the desired position.

The usual and preferred form of the core opening is that shown in Fig. 2in which one edge 13 of the opening is parallel with the axis ofthe-core, while the other edge 14 is oblique thereto. It will, ofcourse, be understood that this may be departed from, the essentialfeature being the difference in angularity with respect to the axis ofthe roll between the edges 13 and 14. It will also be understood that itis not necessary that the difference of angularity extend clear from oneend of the core to the other. In Fig. 5 I have shown a modification inwhich one edge 13 is parallel with the axis of the core throughout,while the other edge has an oblique portion 14 and a portion 15 parallelwith the portion 13. This form is advantageous for some purposes,-forinstance, this form of core could be employed either with a xture havingthe usual flat parallel sided supporting member, or with a supportingmember specially designed with one edge oblique either in part orthroughout.

The core is constructed of two sheets 16-17 of cardboard or otherdesired material, the two sheets being preferably formed from a singlestrip bent in the middle, as at 18, (see Fig. t). Intermediate the sideedges of the strip the sheets have coinplementary offset portions which,when brought together, form the longitudinal opening 12. One of theedges, 16, is conveniently provided with tongues 19 cut from the blank,and the other sheet 17 with complementary slits or openings 20. lVhenthe strip is bent at 18 to bring the two sheets 16-17 together thetongues 19 may be inserted through the slots 20, as will be wellunderstood by reference to the enlarged sectional view Fig. 3. Thiscauses an interlocking between the two sheets and obviates the use of anadhesive material between them to secure them together. rIhis not onlysimplies and reduces the cost of manufacture, but I ind that itfacilitates the mounting of the roll in position. Where a core is madeof two sheets glued together except at the offset portions by which thecore opening is formed, it is often exceedingly diflicult to get theroll started into place, this being for the reason that the core is aptto get slightly crushed and the offset portions forced together, thuspractically closing the opening. In my present invention it is quite asimple matter to spread the two portions of the core slightly apart tostart the roll in place so that even should the two elements be crushedquite flat they can still be quickly and readily inserted into place,the supporting member spreading the offset portions apart without anydifficulty once the roll has been started into position.

What I claim is:

1. An oval roll comprising a substantially lat core having alongitudinal substantially flat opening therethrough disposedeccentrically width-wise thereof, the side edges of the opening beinginclined the one toward the other, and a strip of paper, wound aroundthe said core.

2. An oval roll comprising a substantially flat core "having alongitudinal substantially Hat opening therethrough disposedeccentrically width-wise of the core, portions of the side edges of thesaid opening being out of parallel, and a strip of paper, wound aroundthe said core.

3. A core for oval rolls having a substantially flat longitudinaltapered opening therethrough, the axis of the taper being oblique to theaxis of the core.

LI. A core for oval rolls having a substantially iiat longitudinalopening therethrough, one of the side edges of the opening beingsubstantially parallel with the axis of the core and the other obliquewith respect thereto.

5. A core for oval rolls having a substantially hat longitudinal taperedopening therethrough, the axis of the taper being oblique to the axis ofthe core, and the said opening being disposed eccentrically width-wiseof the core.

6. A core for oval rolls having a substantially flat longitudinalopening therethrough, one of the side edges of the opening beingsubstantially parallel with the axis of the core and the other obliquewith respect thereto, the said opening being disposed eccentricallywidth-wise of the core.
